HOT WORK PROCEDURE

PURPOSE

This procedure provides guidance for a safe operation of welding and

cutting equipment and defines the minimum requirements for conducting

welding, cutting, grinding, electrical tool operation and other types of hot

work.

SCOPE

This procedure applies to all Brieser construction and maintenance projects

where the host facility does not have an adequate Hot Work Procedure and a

potentially hazardous atmosphere or restricted location may exist. If host

facility deems an area a free burn zone or the like a Brieser Hot Work Permit

must be filled out in this instance. Hot Work shall not be performed until a

Hot Work Permit is obtained from our customer/host/facility/client. If a

customer Hot Work Permit is being used, it shall be compared to this

policies Hot Work Permit and verified that all sections are as stringent as or

more stringent than this policy.

DEFINITIONS

1. Hot Work

a. Any activity within a hazardous or restricted area which Could

potentially produce a spark or ignition source;

b. Involves a hot surface;

c. Involves an open flame.

2. Hazardous or Restricted Location

a. These are areas where flammable, combustible or explosive materials

or atmospheres are present or may become present and significant fire

and/or explosion could occur if ignition sources are introduced.

b. Typically a restricted area is designated Class I or Class II Electrical

area.

3. Fuel Gases

Section 23


a. Acetylene – Acetylene is an unstable gas when compressed above 15

psig. Cylinders must be stored in an upright position with caps on.

b. MAPP Gas – MAPP is a stabilized mixture of methyl acetylene with

considerably less tendency to backfire. Maximum allowable pressure

is 94 psig versus 15 psig for Acetylene. Cylinders must be secured

and stored in an upright position with caps on.

4. Industrial Gases

a. Oxygen - Oxygen itself is not flammable, but the presence of oxygen

accelerates the combustion reaction. Oil and grease, in the presence

of oxygen, become highly explosive. Oxygen must not be allowed to

contact petroleum based substances. Cylinders must be secured and

stored in an upright position with caps on.

REQUIREMENTS AND RESPONSIBILITIES

All employees performing hot work must comply with the following written

program:

1. Hot work shall only be performed after the work and area has been reviewed

and approved by an authorized person and a hot work permit issued.

2. In areas where a flammable or explosive atmosphere may be present, Hot

Work shall only be performed after the area where work is to be performed

has been checked with a combustible gas monitoring instrument

(L.E.L.meter) and a reading of 0% L.E.L has been obtained.

3. A copy of the hot work permit shall be posted at the operation at all times.

4. A new permit must be obtained:

a. If work area conditions change.

b. Permits are valid for a maximum of 30 days. Regardless of conditions

GUIDE FOR WELDING AND CUTTING

1. Setting Up Equipment

a. Prior to operating gas cutting equipment all employees must be

trained & knowledgeable in the Gas Cutting Torch Safety Information

in the Brieser Construction Company Training Manual. Appropriate

safety procedures must be reviewed and understood prior to use of

this equipment.

b. Operators of equipment should report any equipment defect or safety

hazards and discontinue use of equipment until its safety has been

assured. Repairs shall be made only by qualified personnel.

c. Momentarily open and close (called cracking) the manifold or

cylinder valves before attaching hoses or regulators. This dislodges

any loose contaminant that is present.

d. Release the regulator adjusting screw before opening the manifold or

cylinder valve.

e. Open valves slowly. Don’t stand in front of the regulator when

opening the valve.

f. When using fuel gas do not exceed 15 psig on torch side gauge.

Reverse flow check valves must be at the regulator end of both fuel

and oxygen hoses. It is strongly recommended that they also be used

at the torch end of the lines.

g. Purge your fuel-gas and oxygen lines.

h. Always light the fuel gas before opening the oxygen line.

i. Never use oil or grease around fuel gas/oxygen line.

j. Never use oxygen as a substitute for compressed air.

k. Keep heat, flames, and sparks away from hoses, regulators, tanks and

combustibles.

l. Make sure all hose, cylinder, and regulator attachments are tight and

not leaking.

m. Cylinders must be secured and stored in an upright position with caps

on when not in use. Oxygen cylinders in storage shall be separated

from fuel gas cylinders or combustible materials a minimum distance

Section 23


of 20’or by a noncombustible barrier at least 5’ high having a fire

resistance rating of at least one half hour.

n. Cylinders containing oxygen or acetylene or other fuel gas shall not

be taken into confined spaces

o. The employee must close the valve on all cylinders and remove hoses

and torches from a confined space when work is not being performed

2. Safety Considerations

a. Never begin any welding or cutting without the proper permits.

b. Always check to see that you have appropriate fire protection

equipment immediately available before doing any welding or cutting

or hot work.

c. A fire watch must be present during the entire welding or cutting or

hot work and stay in area for a minimum of 30 minutes after welding

or cutting or hot work has stopped

d. Welders must not wear synthetic or disposable-type clothing.

e. Welders must wear appropriate PPE which may include appropriate

helmet or goggles with correct shaded lens, welder’s gloves and

welder’s coat. Refer to the Brieser Construction Training Manual for

specific filter lens requirements. Job site conditions may warrant

additional PPE. PPE matrix is also available as an aid during Hot

Work operations

f. Never take short cuts. Follow procedures as outlined

3. Health Considerations

a. Always obtain a Safety Data Sheet for the material you are welding or

cutting on.

b. Specific hazards to look out for during hot work activities

i. Never weld, cut, grind or essentially disturb materials that have

Lead based paint on them

ii. Never weld, cut, grind or essentially disturb materials that have

Cadmium coatings. Cadmium is frequently used as a rust-

inhibitive agent on steel but can be an alloy as well.

Section 23


iii. Never weld, cut, grind or essentially disturb materials that

contain zinc. Galvanized metal as well as brass are top

candidates for this metal in our industry.

ELECTRICAL SHOCK HAZARD

1. Almost all electrical currents present some degree of potential shock hazard.

a. Open circuit voltages should not exceed 100 volts DC or 80 volts AC

b. Welding units that are powered by A.C. must be adequately grounded,

and to change the polarity, the unit must be shut down

c. G.F.C.I.'s (Ground Fault Circuit Interrupters) cannot be used on

welding machines with DC current.

d. Grinding, cutting or portable electrical equipment must be double

insulated or use G.F.C.I. `s.

INERT AND TOXIC GAS EXPOSUE

1. Many welding procedures require an inert gas, such as argon and/or helium.

These gases present an asphyxiation hazard.

2. Large diameter pipe will contain large volumes of inert gas and a greater

potential for asphyxiation.

3. Temporary enclosures over field installations should be checked for oxygen

level before use and monitored continuously when in use. A confined space

entry permit may be required in these situations.

4. Argon will register "hot" when checked using an explosion meter, but will

measure correctly when using an oxygen meter.

TRAINING

Assigned fire watchers must be trained in the use of fire extinguishing

equipment and familiar with the facilities for sounding an alarm in the event

of a fire.

Individuals performing welding/cutting must be suitably trained in the safe

operations of their equipment and the safe use of the process. Refer to the

Brieser Equipment Training Manual

Section 23


A Hot Work Permit must be issued prior to any Hot Work being conducted on Brieser property or at a jobsite by any person,

employee, or contractor. Hot work is any operation that generates heat, spark or open flame. This includes, but is not necessarily

limited to welding, cutting, brazing, grinding, soldering, heat gun use and similar activities.

Before initiating Hot Work, determine if there is a safer way to complete the work.
